T0 all 'whom it may concern.'

Be it known thatl, VALDMLAR D. KMENTT, a citizen otl the United Stat-es,residin at Akron, in the county of Summit and btate of Ohio, haveinvented a certain new and useful Heel- Mold-fashering Device, ot whichthe following is a specification.

This invention relates tor means for accurately positioning a largenumber of small artic-lesran example being the placing ot washers uponheel mold pins preparatory to the molding and vulcanizing of rubberheels wherein the washers are imbedded to serve as abutments tor the"heads of the nails by which the heel is secured to the shoe.

Machines heretofore devised for this purpose have not proved entirelysatisfactory. and it is the object of my invention to overcome theirdefects by the provision of an appliance which is both rapid andaccurate in its operation and is adapted to be made in a compact,readily portable form, my invention in some aspects heilig au improvement upon the type of device shown in patent to Olin. No. 1,159,077 ofNov. 2. 1915.

Ot the accompanying drawings:

Fig. 1 is a plan view ota preferred embodiment of my invention.

Fig. 2 is a vertical section on line 2 2 of Fig. 1, showing the parts atone stage ot' the operation.

Fig. 3 is a similar view of the device in position upon a mold. showinganother stage ot the operation.

Fig. 4 is a horizontal section on line 4 4 showing an intermediate stageoie the operation.

Referring to the drawings, 10 is a cylindrical casing. provided with ahandle 11 and with a bottom or base-member 12 formed with a guide-boss13 adapted to tit into the heel cavity 1% of a mold 15 to position thedevice. said casing and base-member constituting a frame structure. Saidbase member 12 is formed with holes 16, 16 ot' suli cient size t'reelyto permit the passage and lateral play ot' guide tubes 1T. 1T suspendedfrom parts ot' the device presently to be described, said guide tubesbeing internally beveled at their bottoms to tit the conical bases ot'the mold-pins 18. 18 (Fig. l) and thus adapted to be individually guidedinto position upon said pins. and preferably weighted at their lowerends. as is indicated by their thickened walls. to facilitate theirsettling` in place upon the pins. 19 is a washer in molding positionupon one of the pins.

'ithin the casing l() is fitted a cylindrical slide 20. which may beformed of tubing, the upper portion of said slide being vertlcallyslotted at 20ato embrace the arms of a spider 21 fixed in the top ot thecasing 10.

the slide Q0. just above the guide tubes 1T.

is a relatively-thick plate 25 formed with downwardly and inwardlyinclined washerguiding apertures 26. 26 whose upper ends are in twocircular series and whose lower ends are located directly over themouths of the guide-tubes 1T, which latter are tiared. as shown, tofacilitate the entrance ot the washers. Secured within the slide.20,/"above the plate Q5. and spaced-therefrom to accommodate a thinoscillatory transfer plate or slide 2T. a magazine bottom-plate 2Stoi-med with two circular series of apertures Q9. 29. 3U. 30.circumterentially aligned with and otlset t'rom the guide apertures QGin the plate. 25. cach aperture being adapted to hold a stack of washersas indicated at 3l. Fig. 2. The magazine bottom-plate 28 is also toi-medupon its upper t'ace with an annular tiange or ridge 32. separating thetwo circular series of apertures Q9. 30, for directing the washers intosaid apertures. and on its bottom tace is termed with shallow. annularchannels 33. $33 connecting the respective apertures in each series andpermitting.

the transt'cr ot' the washers from the magazine apertures 29. Ik() tothe dischargeapertures lo by the oscillatorv transfer plate 2T.

.which latter preferably is ot less thickness than the thinnest washersused. in order to avoid engaging more than one washer at a time andchoking the device. the channels being ot such depth as not to permitthe passage of more than one washer ot any thickness used.

The transfer plate QT is 'formed with apertures 2T. 2i. slightly largerin diameter than the washers. and may be moved to register saidapertures with the magazine apertures 29, or with the guide apertures26. Said transfer plate is centrally secured to a hollow shaft or sleeve34 rotatably stepped in a countcr-bore at the center of the plate 25.This sleeve is formed near its upper end with helical cam grooves 35,enacting with cam rollers 36, 36 on the spider 21, in which said sleeveis also journaled, to turn the sleeve and the transfer plate 27 as theslide 2O is raised and lowered with respect lowermost washer of eachstack.

to the casing 10. Also secured to the sleeve 34 is an oscillatory,annular, webbed agitator or paddle S7, rotatably fitting the interior ofthe slide 2O and marginally formed with an inwardly sloping base flange38 for directing the washers into the magazine apertures 29, 30.

Extending through the sleeve 3l and the plates 25. 22, is a side-bolt 39having secured upon its upper end a hand knob 40 adapted to abut againsta nut al,v on the bolt to lift the latter' and also adapted to bear uponthe top of the sleeve 3l and force the latter, the slide 20, and theparts carried thereby, downward in the casing 10. The

bolt 39 is formed with a squared portion 39" sliding in square aperturesin the plates 22 and 25, to prevent its rotation and that of a disc 42Ysecured upon the bottom of said bolt. this disc being formed with holesloosely enclosing the respective guide-tubes 17 and adapted to abut theflanges 24 on the latter to clamp said guide-tubes in position againstthe bottom plate 22 of the slide 20 and raise the latter in the casing10.

ln the operation of the device a supply of washers is placed inthe upperpart of the slide 20, constituting the magazine, and the hand-knob 4()is raised. which first lifts the bolt 39 relatively to the sleeve 3st toraise the disc d2 and thereby clamp the guidetubes 17 against the plate22. The further raising of the hand-knob 40, by contact of the flanges24 withv said plate` raises said slide and the sleeve 34 seated thereon,relatively to the casing 10, which meanwhile is held down by the handle11. Thereby, through the cam action of the grooves 35 and rollers 36, arotation of nearly 90 degrees is given to the sleeve 34, the transferplate 27 and the agitator 37, agitating the washers in the magazine tocause'them 'to form instacks in the magazine apertures 29, and bringingthe several apertures of the transfer plate into registry with those ofthe magazine. plate to receive therefrom the I prefer to have themagazine apertures 29a11d the discharge apertures 26 spaced asubstantial distance apart, in order to secure a substantial movement ofthe agitator. lVith the hand-knob 40 and the slide 2O elevated. theentire device is then placed upon a mold cavity, the boss 153 enteringtherein to position the device as a whole, and the hand knob is thenforced downward, rst unclamping the guide tubes 17 and lowering themtoward the mold pins in advance of the slide. Further downward movementof the hand knob 40, now in contact with the sleeve t, forces the slide20 downward until the guide-tubes settle in position on the pins 18, thebeveled walls of the former coacting with the conical bases of thelatter to position the tubes,

and the base plate 22 thereafter seats -uponvl 4the flanges 2A of theguide tubes 17 and clamps the latter in the position 'they have assumedupon the pins. At' approximately the same time, the lowering of theslide 20 80 upon the mold cavity by the handle 11. rlhe disc 42, firstrising with respect to the slide,

clamps the guide-tubes 17 against the slide in the relative positionswhich have been given them by the conical pin bases, and further liftingof the hand-knob 40 carnes the slide and said guide-tubes upward inthose relative positions, while the frame structure is still held inplace upon the moldcavity, the tubes being thus accurately guided asthey are lifted from the pins, in order not to knock the washerstherefrom.
